<h1>Version 4.2.0</h1>
<h2>About WSO2 Complex Event Processor </h2>
<p>WSO2 CEP is a lightweight and easy-to-use Open Source Complex Event Processor
   (CEP) available under the Apache Software License v2.0.</p>


<p>WSO2 CEP 4.2.0 is developed on top of the revolutionary
    <a href="http://wso2.org/projects/carbon">Carbon platform</a>
   and is based on the OSGi framework to achieve the
   better modularity for your SOA architecture. This also contains a lots of new
   features and many other optional components to customize the behavior of the
   server. Further, if you do not want any of the built in features, you can
   uninstall those features without any trouble. In other words, this ES can be
   customized to your SOA needs.</p>
<h2>About WSO2 Carbon </h2>
<p>WSO2 Carbon is a component based Enterprise SOA platform. The
   design of
   WSO2 Carbon focuses on separating the key functionality of the SOA
   platform
   into separate pluggable Carbon components that can be mixed and
   matched, like
   customizable building blocks. This allows you to add only the
   functionality
   you need to start up, and continue to add product capabilities
   as your
   requirements grow. This helps a business to quickly adapt to
   changes.</p>
<p>OSGi is used as the underlying core modularization technology
   to build the
   Carbon platform. The Carbon framework is shipped with Eclipse Equinox
   by
   default, but can be supported on Spring dm Server, Felix or Knoplerfish
   if
   required. The OSGi technology even allows you to write your business
   functionality as an OSGi component and deploy it in the existing Carbon
   platform. </p>
<p> For a quick start on using the WSO2 Carbon
    platform, the Carbon components are pre-assembled into the following
    products: </p>
<ul id="CarbonProducts">
    <li><a href="http://wso2.org/projects/registry">WSO2 Governance Registry </a></li>
    <li><a href="http://wso2.org/projects/wsas/java">WSO2 Web Services Application Server </a></li>
    <li><a href="http://wso2.org/projects/esb/java">WSO2 Enterprise Service Bus</a></li>
    <li><a href="http://wso2.org/projects/bps">WSO2 Business Process Server</a></li>
    <li><a href="http://wso2.com/products/business-rules-server/">WSO2 Business Rules Server</a></li>
    <li><a href="http://wso2.org/projects/identity">WSO2 Identity Server</a></li>
    <li><a href="http://wso2.com/products/data-services-server/">WSO2 Data Services Server </a></li>

    <li><a href="http://wso2.com/products/mashup-server/">WSO2 Mashup Server  </a></li>
</ul>
<p>You can assemble your own products by combining
   components and
   deploying them in a preferred architecture. </p>
<p>The WSO2 Carbon platform gives maximum flexibility to adapt
   the middleware
   to your enterprise architecture, rather than adapt your architecture to
   the
   middleware. </p>
